SPECIFICATION forming part of Letters Patent No. 760,827, dated May 24,1904.

Application filed February 21,1903. Serial Nol44=,5l3. (N0 model.)

To all w/Lnm it may concern/: Be it known that we, THoMAs VICARS andJOHN VIOARS, the Younger, subjects of the King of Great Britain,residing at Earlestown, in the county, of Lancaster, England, have invented new and useful Improvements in Biscuit Stamping and CuttingMachines, of which thefollowing is. a specification.

The invention relates to machines in which hollow cutters surroundingthe stamps, embossers, or impressors act first to detach or strip offthe stamped" sheet of dough from the stamps and then complete thecutting out of the biscuits from the'sheet; and our invention consistsin new constructions, arrangements, and operations of mechanism toelfect these purposes and to regulate the mechanism ac.-

cording to the. thickness of the sheet of dough from which the biscuitsare-being cut.

The accompanying drawings illustrate several arrangements of mechanismaccording to our invention... v

. Figure 1 isganend view of one arrangement of partsinwhich stationaryadjustable stamps are used. I Fig- 2 is acentral longitudinal section'of the sam,e, and Fig. 3 is a plan of the the views.

In carrying out our invention, as regards the stampmg and cutting wearrange the cutting:

table to reciprocate in guides or otherwise tosheetof dough 3.is causedto travel intermittently in the usual way. 4 represents brackets or abearer supporting the table- 7 5 represents guides in or on themain-framework 6, in which the brackets 4: can move up or .head13,which. is movableupand down in slides 14 in the frame 6 in, the usualway by rods 15, connected thereto and to the eccentrics 16, secured tothe shaft 9, which latter is rotated by any suitable gearing. 17represents the stamps or impressors for stamping the design on thebiscuits, securedby-rods 18 to a. plate 19, .which is in turn connectedby rods 20 to a cross-head 21, attached to the frame 6. The rods'20 arescrewed at their upper ends and engage with internally-screwed sleeves'22, which are rotatablein bosses or bearings 23 on the cross-head 2124: represents toothed wheels secured to the sleeves 22 by nuts 25 orotherwise, as convenient. The wheels 24 gear into idle wheels 26, whichin turn gear with a toothed pinion 27, mounted on apin 28 on thecross-head. 29 is a worm- -wheel secured to the pinion 27 and operatedby-a worm 30 on a shaft 31, rotatable in bearings 32 by a hand-wheel 33.Thus by rotating, the hand-wheel 33 the sleeves 22 are rotated and therods 20, plate 19-, rods-'18, and

stamps are adjusted to any desired distance from the table 2.Stripping-plates for stripping the dough from the outside of the cuttersmay be used; but these may be of any usual kind and for clearness arenot shown. action of the parts is as follows: The cams 8 raise up thetable 2 and press the sheetof dough against the stamps 17, thusimpressing the design on the biscuits. The table then begins to descend.In the meantime the eccentrics 16 are drawing down the cutters 11 fromtheir highest position, and as the edges of the cutters pass the levelof the stamp-faces they detach or strip Off the stamped part of thesheet of dough from the stamps if it should adhere stamps 17 are movedup or down, so that the The , owing to form of eams- 8, has been broughtto rest a short distance below the stamps and remains there until thecutters by continued downward movement cut out the biscuits from thesheet. The cutters then rise, and if the biscuits adhere to the cuttersthey are stripped ofi? by the stamps. The table then descends to itslowest position, the sheet of dough is advanced, the table again rises,and the operation is repeated.

It is to be observed that in all the arrangements herein described theaction on the dough is the same or similar to that above described, andthe cams or other operating devices must be so shaped and arranged as toeffect the operations in the sequence stated.

Referring to Figs. 4 and 5, in this arrangement the plate 19, whichcarries the stamps 17, is rigidly fixed to the framework 6, so that thestamps have no motion whatever. The cutter-bar 12 has connected theretorods 34, -screwed at their upper ends, which engage in screwed sleeves35, rotatable in bearings 36 in the cross-head 13. To the sleeves aresecured worm-wheels 37, which are operated by worms 38, secured on ashaft 39, rotatable in bearings 40 on the cross-head 13. 4:1 is ahand-wheel for rotating the shaft 39. The cutting-table 2 is supportedon screwed rods 20*, which engage with screwed sleeves 22, rotatable inbearings 23 in the brackets or bearer or support 4. 24: representstoothed wheels formed with or secured to the sleeves 22 and gearing witha central wheel 26, which in turn gears with a pinion 27, rotatable on apin 28 on a bracket 21*, fixed to the bracket 4. 29 is a worm-wheelsecured to the pinion 27 and operated by a worm 30, secured on a shaft31, rotatable in bearings 32 on the bracket 21 by the hand-wheel 33.Thus by rotating the hand-wheel 33 the sleeves 22 are rotated and thetable 2 raised or lowered with regard to the bracket 4:, so that thedistance of the surface of the table from the stamps can be regulatedaccording to the thickness of the'sheet of dough, and by rotating thehand-wheel 41 the sleeves'35 are rotated and the cutters are raised orlowered to correspond with the raising or lowering of the table. Theshafts 31 39 may be geared together by any convenient gearing which willinsure simultaneous rotation of both shafts, but

which will allow of independent vertical movement of each shaft, so thatboth the cutters andcutting-table can be regulated by one hand-wheel.

O'ur invention is not confined to the exact details of constructionabove described, as it will be obvious that many different equivalentarrangements of mechanism may be made to effect the desired motions ofthe cutting-table and cutters and that other equivalent arrangements ofregulating mechanism may be used at any convenient point in theconnections between the operating-shaft and the cutters or stamps ortable without departing from the nature of our invention.

We do not claim, broadly, the method of first stamping and afterwardcutting out biscuits; but

What we do claim, and desire to secure by Letters Patent, is-

1. In biscuit stamping and cutting machines the combination of areciprocating cutting-table, reciprocating cutters, stationary stampsdisposed within the cutters and gear for operating the table andcutters, substantially as described.

2. In biscuit stamping and cutting machines the combination of areciprocating cutting-table, reciprocating cutters, stationary stampsdisposed within the cutters, gear for operating the table and cutters,and mechanism for regulating the position of the stamps with relation tothe cutting-table, substantially as described.

3. In biscuit stamping and cutting machines the combination of areciprocating bearer, a cutting-table supported on the bearer,stationary stamps disposed within the cutters, reciprocating cutters,gear for operating the bearer and table, and cutters, regulatingmechanism between the operating-gear and the table, and regulatingmechanism on the connections between the operating-shaft and thecutters, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
